The execution of geotechnical works involves the need for particular requirements. Employed techniques, although referable to those usually used for the execution of impermeabilization and consolidation works, are exasperated, in their application fields, by the remarkable depths to be reached, by the nature of the soils to be passed through and by the location of the dams that are generally in poorly populated areas or far from main inhabited centres.

Trevi has a wide range of means and resources that allow performing any kind of geognostic survey.
The diversification of the various types of fitting of our drilling rigs allow us to choose the most suitable equipment, in accordance with the type of soil on which we have to work.
